DISK WHEEL.

Applica/nan mea January 29, 192s. seriai No. 615,493.

My invention has lo do particularly with the securing ot an intimate Contact between the rim and disk throughout the peripheral extent of the latter, accompanied with a re- .silient reaction upon the securing clips and bolts, whereby a firm connection is assured and is maintained unirnpaired through an extended period of use.

W'here one flat surface is bolted at intervals to a second flat surface andthere exist stresses tendingl to separate the surfaces, as is the case with the abutting faces of a wheel disk and rim, not only do the surfaces between the bolts tend to separate, leaving portions out of contact, but the connections at the bolts are Without life and the nuts are apt to Work loose under conditions of use.

By my invention I impart to at least one ot' the contact members, preferably the more flexible disk, a circumferentially wavy or un dulate contour, the wave lengthscorresponding preferably to the distance between the securing bolts and the crests of the waves corresponding preferably to the location of the bolts, whereby when unstressed the adjacent surfaces of the disk and rim will be in contact between but ont of contact at the bolts, and as the bolts are tightened the waves of the disk will be flattened until a continuous line of contact results, in which condition there will be a close fit of the surfaces one against the other with a resilient live reaction at the bolts acting to prevent the working loose of the nuts.

The invention will be readily understood by reference to the accompanying' drawing and the following detailed description predicated thereon wherein is set forth a )referred embodiment of the invention. t) viously, however, the invention is snsce itible of embodiment in other structural orms wherefore the description and drawing are to be taken in an illustrative and not in an unnecessarily limiting sense. In the drawing- Fig. 1 is a fragmentary front elevation of a disk wheel embodying the invention;

Fig. 2 is a radial section through that portion of the disk Wheel illustrated in Fig. 1;

Fig. 3 is a devolo d sectional plan taken on the line 3 3 of ig. 2;

Fig. 4 illustrates in radial section a modified embodiment of the invention, and

Fig. 5 is a fragmentary front elevation of a disk wheel embodying;i the invention iu- `spondingly inclined portion 14 ot' a tire-car rying rim 15. A rim-retaining clip, which may be in .the form of separate segments 1G or of an annulus 1G, bears at its inner edge 17 upon the disk 11 and at its outer edge 18 upon the forward edge of the rim 1 5, by means of the clamping action of the bolts t9 and the nuts 20, serves to force the rim rearwardly upon the disk and draw the peripheral portion of the disk forwardly against the rim, the inclined faces of the two at 13 and 14 riding upon each other by a Wedge action.

In order to assure a continuous intimate Contact between the abutting :tacos of the parts 15% and 1-1, the peripheral portion of the disk at its margin 13, and preferablv throughout its peripheral portion 12. is given a normally undulate or wavy contour as viewed eircumierentially in the plane of the Wheel.

.The Ware lengths of this uudulate portion correspond to the distance between the bolts 1 9, as most clearly shown in Fig. Ii und the crests of the sucressive waves dcrur at the bolts, the crests of the waves heini,r indicated at 2l and the troughs ot' the waves at 22.

It follows that when the rim is first placed upon the disk and the parts remain unslressed the disk periphery at 13 contacts` with the rim only at the points Q2 corresponding to the troughs of the waves, but asthe bolts 19 are drawn houle by means of the nuts 2O the Waves are liattened until the disk portion 13 at the points 21 etrrespoudingr to the crests of the Waves also contact with the riin. This is not only insures a close tit of the rim upon the disk at all points about the periphery but also results in a resilient reaction upon the bolts and nuts which tends to prevent the loosening of the latter in use.

While the undnlate periphery of the disk is. in the particular embodiment of the drawing. shown ns hearing upon the l'ini adjueent he front of the lniier, ii. will be evi-- (lent ilie uinlnlnie peripheral margin ofV u wiiler liSk i'lnnge or felly such as is in Colninon lise might engage the rim nenr its rear elige ii li is nimo eviilent `Lhe nniinlaie eonionr might he impartial to ihe eontueting raxrfnre of either (link or rim. or hoih` In nhieh laiier ense n pariinl nesting; of the waves would :insist in overcoming any tend envy of the riin lo Creep eirenmlereniinlly of ille ilisk as Fhon'n in Fig. 4.
